RPE: Moving template part to a new Data Scheme request

Hi everyone,
I had an RPE template working perfectly with a Data Source (DOORS 1 $15 Module/Object). When adding new functionality, I need to include some DOORS Module fields into the Data Source so I perform the DOORS Scheme Discovering functionality which includes the a new Data Source (DOORS 2) instead of upgrading the existing one (DOORS 1).
First, I include the new functionality using a container where I drag and drop the new Data Source: DOORS 2 $20 Module). Up to here, everything is fine.
But, I cannot just drag and drop the new DOORS 2 Module/Object to the old container functionality.
Second try, I create a new container with the DOORS 2 Module Object request and copy and paste the olf functionality. However blocks contains only conditions and texts but none request and assingments.
I am pretty sure that I am having a quite small failure. Can anyone help me to discover it?
Thank you very much.
